This commit fix the "Unsupported M2M command 1" raised `Form` helper.
The `onchange()` method will in fact emit UPDATE command for many2many
fields when the value submitted an the one in database has changed
(this is the case for example for nested m2m in form views)

Issue is specifically in the case of an onchange removing a record in
an o2m in an o2m (so a sub-o2m) if loading an *existing* record in the
SSF: since the server pretty much only returns a REMOVE_ALL followed
by the records to keep or create, conserving the removal information
requires diffing the value currently stored in the form and the result
fo the onchange.
Diff which was properly done for top-level o2ms, but not for the ones
below that (apparently forgot this bit when improving support for
nested o2ms earlier this year).

In the SSF, o2m updates get initialized with no values (1, id,
{}). The record data is only fetched when the "record" gets updated
explicitly from which updates will hopefully get properly tracked &
saved.
However if the "record" was first initialized through an onchange
values which are updated by the onchange (diverging from the db) those
would not get tracked and thus wouldn't get saved when the record is
saved.
* use more specific placeholder (None) for "o2m records to update but
we don't have values yet"
* once we have values, always store them as an update-tracking dict
* if we don't have values yet for an o2m and an onchange is trying to
write to it, initialize with values from database first (might
eventually be a good idea to initialize upfront though there's the
question of what happens for default values and recursive views)
* mark anything coming back from the onchange and differing from local
values as changed (so they get sent out on save)
* properly reify parent values for onchange instead of sending them
as-is
* the evaluation context for contexts (and domains) needs properly
formatted values so use `_values_to_save` to get them, however it
cares about neither required-ing nor filtering out e.g. unmodified
fields, therefore add an awful toggle to handle this
Task 2150302
Probably todo in the future:
* better UI for change-tracking dict, should have "snapshot"
support (to freeze / discard previous changes)
* cleanup save, it's unclear that it properly resets the form

m2ms are internally represented as "6" commands, however in domains
it's possible to compare an m2m value to a list of ids (to
investigate: whether this is an artifact of internal webclient repr or
part of the real contract).
Add a workaround in SSF modifier computation to convert the m2m
command storage to a simple ids list.
A better fix would probably have been to represent the m2m as a list
of ids internally (and only convert on load / save) however it not
completely trivial as it has to be done recursively in order to
properly handle an m2m inside an o2m. So it's a complete change of the
internal data model (which should probably go alongide more
fundamental changes e.g. properly handling parent refs, etc...)
Also add very minor support for widgets (mostly so it's possible to
set widget=many2many on an o2m field).

A required boolean accepts two values, True and False, however the SSF
and the web-client assume False to be equal to NULL and treat them
interchangeably.
In the SSF, we verify that a required field is filled by checking that
its value is different from False, however False is a valid value for a
boolean, this means that setting a required boolean to False would never
work in the SSF.
This commit overcomes this issue by simply skipping the check for fields
of type boolean.

The SSF would correctly filter out readonly fields when saving a
toplevel form, however it could not remove readonly values when saving
o2m pseudo-records to the parent form (as these would be expected to
remain available for reading upon the next edition and whatnot), so
these values would get sent in 0/1 commands.
Filter out these fields during the parent / toplevel save call.
Complexity notes:
* evaluating readonly modifiers requires the entire record, so
unchanged fields still have to be written back to the parent form
and be filtered out when *it* is set up for save, an alternative
would be to store the `changed` and `readonly` flags alongside the
record dict, and have the post-process only override the
pre-computed readonly flag using force_save
* had to fix a test to match the new behaviour, the post-edition
states turns out to be in line with the client's behaviour (or how
it looks anyway)
Fixes #32019

The extra setup probably affects any o2m whose edition view itself
contains an o2m, but most likely to blow up entirely on models with
some sort of tree structure (parent/child relationship): the SSF
eagerly loads and setups the o2m's view, and the o2m's o2m's, ... ad
infinitam.
A better / cleaner fix would be to set up the subview on-demand (and
possibly cache it), but the rest of the o2m stuff is unlikely to work
correctly recursively so just don't recurse the o2m view setup at all
for now.

PRs #28645 and #31494 were not applied to 12.0, but there's no reason
not to, they should only fix things (make behaviours more in-line with
the regular client), and since o2m is an area where more fixes are
needed and it would be nice to have them in 12.0...

The SSF would properly mark its own records as deleted, but it would
not properly handle deletion requests coming from an onchange, and it
would not necessarily convert DELETE_ALL commands (5) into the proper
sequence of individual (2)s matching existing records.

* Form would entirely mis-interpret the server's response to some
results: for unmodified o2m records the server sends a (4), which was
un-interpreted by Form, leading to the o2m record being lost entirely
(as it rebuilds the entire o2m on setting)
* on record creation, every field (except id) is considered modified not
just the fields set by default_get
* Form diverged from actual client in that it would send (1, id, {}) for
unmodified o2m records, actual client sends (4, id, False)
* datetimes should be sent stringified
* onchange should not be triggered when none of the modified fields is
flagged as an onchange trigger
* the default value for numerical fields is 0 not False
* convert m2m onchange results to (6, False, ids) instead of (6, 0, ids)
for ease of diffing with actual client's data
There are still a few odd divergences in the actual invocation of
onchange when attempted on an SO, but they look to be of low relevance
/ risk.
Note: making integer fields "required" has pretty much no effect
anymore. This is in line with (my understanding of) the client's
behaviour, but required the alteration of test models as the
specific test on required... was using an integer field.

In the normal course of saving-action, readonly fields are stripped
out when sending data to the server. The SSF would reuse the same code
when "saving" O2M lines to the parent record however that is not
correct and would lead to misbehaving views as readonly (non-stored)
fields used as "transients" (storing data within the extent of a
record's edition session) would not behave properly.
Fix by overriding the O2M Form's save so that readonly fields are
kept and stored in the parent record.
Closes #23620

Useful to better test business flows & replace yaml test files:
instantiating records & calling onchanges by hand is very
error-prone (it's easy to miss onchanges, or to manually set fields
which can't be set through the view we're interested in, ...)
odoo.tests.common.Form implements the basic *creation*
flow (fields_get, default_get, onchange) up to saving the record,
including proper handling of the required and readonly modifiers &
their domains.
* edition of existing records, including filtering out unmodified
fields when saving
* possibly buttons
* ensuring the API is convenient
